A sad face is an expression used in electronic communication such as texting and emails to convey an emotion without using an emoticon. Nevertheless, caution should be used when interpreting this term due to wide range of emotions that may be attached to it. It could mean "sad face" as in "I pouted for half a second" or it could mean "sad face" as in "I'm broken hearted beyond belief." "Sad face" is tied with "I am" for the shortest complete sentence in the English language.
He thought she was joking when she texted him "Sad face" but then she threw herself off of a cliff and he always blamed himself for her suicide.
